I have been using rotenone based products for 30 years now for potato bugs/larvae , cucumber beetles, flea beetles, cabbage worms, asparagus beetles, carrot flies and onion flies . Rotenone is derived from natural plant roots and is used in a .7% concentration in this product.
This powder just needs to be lightly dusted over the leaves of the plant and is very effective . The bugs die within minutes of application . I use a small coffee can with small (1/32")holes in the cover to sprinkle it on . It bio-degrades in a few days and needs to reapplied several times during the season . It is safe to use ,cheap,leaves no harmful residue , and is organic sanctioned. A 2kg package will last for several seasons.
